Here is a video I took laying under my car looking up at the drive shaft and differential with the parking brake on and Transmission in neutral. I have and IRS Torson setup all parts bought new from a vender on this forum. This is a video when then car was in go cart stage and now have over 3,000 miles on it. The excess play has always been in the back of my mind but after driving the car it seems to work fine, no clucking noise noticed. I am hoping to get it painted this winter and thought now is the time to make sure everything is correct. Does this look like something I need to look into?
Thanks Dan
